NOAA's Storm Prediction Center has logged 26 separate hail days here since 2010 -- 1.5 a year over 17 years of record. Those days carry 62 separate reports between them, two or three on a typical one. 4 of those 17 years produced none at all. One year dominates the record: 2012 alone produced 6 of the 26 days. The last five years track the long-run rate, with 7 days since 2022.
3 of the 26 days reached 2 inches or more -- 12%, or about one hail day in 9, the last on 2026-09-05. Those big days do not follow the county's usual calendar: most of them fall in April, not May. Golf-ball size is rarer still: 1.75 inches or more on 6 of the 26 days.
